Location: Heywood
Australian Soil Classification: Bleached-Mottled, Eutrophic, Brown CHROMOSOL (confidence level 1)
General Landscape Description: Undulating plains
Site Description: Mid-slope to lower slope, 7%
Land Unit: Condah Basalt
Geology: Quaternary basalt
General Land Unit Description: The undulating plains and rises of the Condah area mainly consist of Ferric Chromosols. On the lower slopes bleached A2 horizons and mottled subsoils are common. On the broad level crests, gilgai microrelief is common.
